Making your bonsai taller

With exposed root bonsai it is possible to create a taller tree. One can simply raise the tree up on its finer root system while keeping it supported with wire until the new roots harden sufficiently to make the trunk stable.

The new roots will need to be covered for some months until they harden off and become adapted to dry air. Once so adapted the alluminum foil can be removed.

Twisting and Turning

When presented with material that is young and lacks interesting features I will search for ones that have twists and turns. Great bonsai can be created from this rather unexciting material. Using wire to shape long and limber pieces is another way to introduce interesting shapes. Another way is to use root cuttings that often have great shapes, The pictures below are all of Ficus ‘Mystery’, a fig that is not identified yet.

The tree with no taper

There are many ways to handle a tree with little or no apparent taper. In this case a Ficus ‘Mystery’ was grown from a very straight and taperless cutting.

Fortunately there were several existing aerial roots that were brought down along the trunk and rooted into the ground. The aerial roots provide a visual thickening to the lower part of the trunk creating some taper that just does not exist. The roots coming off the aerials provide a nice surface flow that helps to visually stabilize the tree.

The bonsai shows some nice taper provided by the aerial roots as well as nice surface rootage.

The Creeping Fig – Ficus pumila/repens

A fig commonly found in many garden centers used as a hanging basket plant is Ficus repens/pumila. Commonly called the Creeping fig. It is one of an assortment of figs that will climb up tree trunks, stone or brick walls and soon cover the surface with a very dense covering of leaves.

It is peculiar also in having two types of leaf. One is the very small heart shaped leaf that it grows as a small cutting and another much larger leaf that grows on sturdier branches that are often not supported on the wall to which most of the plant is clinging.

It an be used to shape small bonsai by allowing the green stems to get woody and to set shape and then to create a canopy from the branches. Getting a large trunk of this species is difficult and I have been looking for one for many  years.

Make sure to keep this plant moist as it does not recover from drying out.

Ficus with rounder leaves

Ficus show lots of natural variations when grown from seed. Leaf shape, leaf size, bark color, vigor etc. can vary greatly from one seedling to the next. This can even occur with seed harvested from the same mother tree.

Some of the leaves are quite round

Here is one of many Ficus virens that I have grown from seed. This individual has a rounder leaf than the normal virens. Its other characteristics are pretty typical for Ficus virens but if one were to just use the leaf shape as a major factor in the identification it might just lead you astray. This is one of the most frustrating features of Ficus, their variability. While making our lives miserable by confusing our identification it is a useful trait for the species as it enables them to modify themselves and perhaps find an environmental niche to exploit.

Creating a heavier branch

Sometimes it is desirable to have a heavier branch and the material is grown in a container, indoors or is just a slow growing variety. In this case the material is Ficus microcarpa ‘Melon Seed’. This is a slow growing, miniature leaf form of microcarpa.

In order to develop it as a bonsai I have a good sized right branch but the left side needs a heavier branch. Fortunately, there are several small branches coming out of the left side that can be fused and form a proper sized branch. The apex of the tree is also too thin but there are no other branches that I can use right now to thicken it up.

The left side has several small branches that are pulled together with electrical/cable ties and with time they will fuse

Proper root positioning

Roots, as with any other part of the bonsai’s design, must be compatible with the overall look and feel of the tree.

In this case, there are one or more roots that do not work with the upright design of the tree.

For all my bonsai and non-bonsai friends traveling to Thailand, I would like to highly recommend a visit to The Bonsai Village, Ratchaburi. The Bonsai Village is named after a ,  a local tree. The bonsai village is a spectacular resort featuring Japanese and Chinese gardens and containing thousands of bonsai trees. The resort covers some 40 acres along the Pa Chee river! 
In the gardens are beautifully displayed bonsai trees of museum quality; in fact it is one of the best tropical collections that I have seen anywhere. The bonsai were developed in Thailand as well as imported from many countries including China, Japan, Philippines, Taiwan, and Indonesia. And close to my heart are large numbers of Ficus trees including Benjamina, Microcarpa, Virens, Religiosa, Racemosa, and Rumphii – to name just a few. They are all displayed in wonderful matched containers.

It will take many hours to view even a portion of the bonsai and gardens but it will be well worth the time to see this international museum quality collection even if you have a few hours to spend.
There are also exquisite accommodations with well-appointed guest rooms, dining facilities, and a Japanese villa in which one can stay. I highly recommend staying at the resort and enjoying the gardens and bonsai.

Root cuttings

Root cuttings are one of the easiest ways to develop a good bonsai from throw away materials. Repotting a fig bonsai is needed every year to 5 years depending upon growth, species, size of pot etc.

On removing some of the larger and more shapely roots the root is potted up with the root hairs in the soil and the cut end sticking out of the soil about 1-2 inches. After 2-6 months the end of the root will sprout new leaves and stems. Over time the new growth can be shaped to be an interesting bonsai. In addition most of the root can be lifted out of the pot to make a longer trunk.

Not all fig species will sprout from roots but natalensis is one that sprouts very easily.

Identifying a Ficus by using the leaves

Fig leaves are very variable from species to species. This is helpful in trying to identify a fig as belonging to a certain species. The problem is that the leaves on even a single plant can show great variation depending upon cultural conditions of light, moisture, growth in a container, wind, etc.

As an example the shot below shows several leaves removed from a single Ficus plant. The variability would make an attemp at a scientific identification very difficult. Many factors must be used to help in correctly identifying a fig. These include the leaf, bark, syconia, stipules etc.

Figs are wonderful plants to use for bonsai but they can infuriating to correctly identify without figs/syconia.
